New planting techniques of Hippophae rhamnoides

Hippophae rhamnoides, Elaeagnaceae, Hippophae rhamnoides, also known as acid willow, acid thorn, is a small berry plant, deciduous shrubs or subtrees.

I. Land preparation

Hole-shaped ground preparation, the cave surface is 50 cm long, 40 cm wide, and the depth of soil preparation is 30 cm.

The row spacing is generally 1m X2m or 1.5m X2m. Can also be ribbon soil preparation, soil preparation depth of more than 20 cm. The time of soil preparation is from 1 quarter to half a year before afforestation, and the effect of soil preparation one year in advance is better.

2. Planting

Planting time can be spring and autumn, spring generally in the pre-germination, soil thawing 20cm to 30cm. Generally, it is better to grow seedlings with a height of 30 centimeters and a ground diameter of more than 0.3 centimeters. Before planting, the planting point should be determined according to the requirements of the planting design, and then the planting hole should be dug on the planting point, and the planting hole can be put into the seedling, then the seedling can be put into the hole, and then the seedling should be slightly raised-down, so that the root system can be fully extended, and the seedling spade should be inserted into the edge of the planting hole a few centimeters, squeeze it, firmly dig the hole with the foot, and finally cover the surface of the hole with a layer of loose soil. This afforestation method is called narrow slit planting. The planting density of general soil and water conservation forest is 2m × 1m or 1.5m Xl m, while that of Hippophae rhamnoides orchard is 2.0m X 3.0m. When building a garden on a gentle slope, it should be planted along the contour line. High quality varieties with large fruit, long stalk, no thorns and high yield must be selected for afforestation in Hippophae rhamnoides orchard, such as Miracle 1, Xiangyang, late ripening No. 1 and so on.

III. Tending of young forests

Weeding and loosening soil should be carried out in time after the survival of afforestation to prevent weeds from growing.

IV. Flat stubble rejuvenation

Flat stubble is usually carried out in the dormant period of trees, but it is best before the soil is thawed in early spring. Flat in the way there are "slice cut", "flower cut", "belt cut" and so on, cut as far as possible to reduce the stubble, and keep smooth. Its branches are generally 50%-60% of their fresh weight when they are air-dried, and there are a lot of branches after being flat, and the growth of the new forest can reach about 0.6 meters in the same year.

5. Common diseases and insect pests

The main diseases and insect pests that harm seabuckthorn are seabuckthorn wood butterfly, seabuckthorn fly and dry shrink disease and so on. The easiest way is to cut down the diseased plants and insect plants and transport them away as fuelwood.
